Taking the font as an example, when therotating element 130 is rotated to correspond to one of thescales 112 of thepen body 110, meanwhile theradio frequency module 120 sends out a signal corresponding to a specific frequency, thereby changing the font in the writing function correspondingly. Thesescales 112 make theradio frequency module 120 send out signals with different frequencies. Then, the signals with different frequencies are received by the digital panel (not shown) and then, the frequencies of the signals are determined, thereby changing the font of the writing function into DFKai-SB, MingLiu, PMingLiu or SimHei.

When the user intends to erase the data, he/she must click the button for erasing data on the digital panel via the digital pen, so as to delete the data to be erased, and then click the button corresponding to the writing function on the digital panel, so as to make the digital pen be switched back to the writing function. Such process of erasing data is relatively inconvenient for the user when using the digital pen.

FIG. 4A is a schematic view of the digital pen inFIG. 3 , andFIG. 4B is a side view of the digital pen inFIG. 4A . Referring toFIGS. 4A and 4B , thedigital pen 300 comprises apen body 310 and aradio frequency module 320. Thepen body 310 has afirst end 312 and asecond end 314, wherein thefirst end 312 is a pen nib of thepen body 310 and thesecond end 314 is a pen tail of thepen body 310 opposite to the pen nib. Theradio frequency module 320 is installed within thepen body 310 to send out a first signal at thefirst end 312 and a second signal at thesecond end 314, wherein a first frequency region of the first signal is not overlapped with a second frequency region of the second signal. - As for the working principle of the
digital pen 300, when the pen nib of thedigital pen 300 touches the digital panel 200 (as shown inFIG. 3 ), and thecircuit module 220 of thedigital panel 200 receives a first signal sent out by theradio frequency module 320 at the first end 312 (i.e., the pen nib), thedigital pen 300 corresponds to a writing function when moving on thedigital panel 200. On the contrary, when thecircuit module 220 of thedigital panel 200 receives a second signal sent out by theradio frequency module 320 at the second end 314 (i.e., the pen tail), thedigital pen 300 corresponds to an erasing function when moving on thedigital panel 200. In short, the first signal makes thedigital pen 300 correspond to the writing operation and the second signal makes thedigital pen 300 correspond to the erasing operation, such that thedigital pen 300 is used just like a pencil, that is, the pen nib is used to write and the pen tail functions as an eraser. In this embodiment, the first signal is in the first frequency region, for example, 120K-250K Hz, and the second signal is in the second frequency region, for example, 40K-80K Hz. - Provided that the
digital pen 300 sends out the first signal and the second signal simultaneously at thefirst end 312 and thesecond end 314 through theradio frequency module 320, thecircuit module 220 of thedigital panel 200 determines whether thefirst end 312 or thesecond end 314 of thedigital pen 300 moves on thedigital panel 200 by comparing the strength of the first signal with that of the second signal. In other words, when the first signal send out at thefirst end 312 and the second signal sent out at thesecond end 314 are received by thecircuit module 220 on thedigital panel 200, the strength of the first signal and that of the second signal are different due to the length of thepen body 310 of thedigital pen 300. Therefore, whether thefirst end 312 or thesecond end 314 of thedigital pen 300 is more close to thedigital panel 200 can be determined through this method. - Since the
radio frequency module 310 of thedigital pen 300 works based upon the electrical power supply, it has a built-in power, such as a battery. For saving power, besides the function of receiving a signal, thecircuit module 220 of thedigital panel 200 further has the function of sending out a signal. Theradio frequency module 320 of thedigital pen 300 senses the signal sent out by thecircuit module 220 of thedigital panel 200 and converts the energy of the signal into the energy for generating the first signal and the second signal, such that a built-in power supply may be omitted in theradio frequency module 310 of thedigital pen 300. -

Referring toFIGS. 5A and 5B , thedigital pen 400 differs from thedigital pen 300 inFIG. 4A in that, thedigital pen 400 further comprises apush button switch 430. Thepush button switch 430 is disposed on thepen body 410 and electrically connected to theradio frequency module 420, and upon being pushed, it is used to adjust the frequency of the signal sent out by theradio frequency module 420 from a first frequency region to a second frequency region that is not overlapped with the first frequency region. Particularly, thepush button switch 430 is a one-way switch, thus, when a user does not push thepush button switch 430, theradio frequency module 420 of thedigital pen 400 sends out a first signal in the first frequency region to make thedigital pen 400 correspond to a writing operation; on the contrary, when the user has pushed the one way switch 432, theradio frequency module 420 of thedigital pen 400 sends out a second signal in the second frequency region to make thedigital pen 400 correspond to an erasing operation. -

Referring toFIG. 6 , thedigital pen 500 differs from the digital pen inFIG. 5A in that, thepush button switch 530 is a two-way switch, which is switched between a first position P1 and a second position P2. Therefore, when thepush button switch 530 is at the first position P1, theradio frequency module 520 of thedigital pen 500 sends out a first signal to make thedigital pen 500 correspond to a writing operation. Additionally, when thepush button switch 530 is at the second position P2, theradio frequency module 520 of thedigital pen 500 sends out a second signal to make thedigital pen 500 correspond to an erasing operation. In this embodiment, the first signal is in the first frequency region, for example, 120K-250K Hz, and the second signal is in the second frequency region, for example, 40K-80K Hz. - In view of the above, the present invention utilizes the radio frequency module of the digital pen to send out the first signal and the second signal at two ends of the pen body of the digital pen respectively, which are then received by the radio frequency module of the digital panel, so as to make the digital pen correspond to the writing and erasing operations respectively, thus, it is more convenient for the user to write and erase data on the digital panel. Additionally, whether the first signal or the second signal will be sent out by the radio frequency module of the digital pen can be determined by the push button switch in the present invention, such that it is more convenient for the user to write and erase data on the digital panel through the digital pen.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
